No good, stater motors are not made to be used for long periods of time, the self destruct if you use it as a weapon motor!

Why the motor in the disc? Why not use a belt?

Has anyone ever used a Red Tape in MvM?
I wanna see what happens.
It's useless in MvM. Might as well be a regular sapper.

ACAMS?
Did you break the internet again?

If I could make one suggestion, it would be to swap the battery and the rx. That will put the heaviest part of the bot closer to the wheels, giving added traction.

This is the Great Pumpkin, built by the same team that made Last Rites. Take it as an example, all it consists of is pretty much what you have, a pair of wheel chair motors, a solid construction, and filled with high quality parts. No active weapon, no exotic materials, I doesn't even have wheel guards. The only thing of note about it is the fact that it runs off of A123 batteries. Here's my last bit of advise, if you are still going to build a heavy, use whatever is left of your budget to invest in armor and batteries, especially the last one. A good set of NiCads, or even better, A123 batteries, will give your bot the amps it needs. I'm not sure if your running your bot on 24 volts or 36, or even 12, but I strongly urge you to invest on good quality batteries. They will last you several builds if properly maintained, saving you money in the long run. Use a quality charger, like the AstroFlight 112 Deluxe(Or the AstroFlight 123, you'll need a balancer though!) and a good power supply like this one, and again, they will last you a long time if properly cared for. That's my two bits. You've already gone farther than most members here, and I really hope that you can make it to ComBots this year.

I've heard really bad things about fake deans connectors. I would REALLY want stay away from those. Plus, I want acceleration like a bullet, rather than a car.

I want over volted B62's because I want acceleration. B16's and 1000RPM gear motors put out plenty of speed, but I want to cover more ground very quickly. Plus, the Kitbot motors with hardening and deans connectors cost 28 dollars, so I figured that I might as well go with the slightly more torquey and better built B62.

Ok, time for an update: Short Stop is almost done, all I need to do for it is get a better battery and bit of nut strip. For ComBots, I was thinking of building a Beetle. So I have some quick questions: How well do the B62 motors take 22.2 volts? Some other beetles seem to handle it fine. I'm going to be using these wheels. Sound good? Also, anyone else use Zippy lipos? I was thinking of using a pair of three cell lipos and wiring them for 22.2 volts.

They are 1 3/4" long by by 12 sixteenths of an inch wide and half an inch tall at the highest point with case. The antenna is about six inches long.

Since changed back my location, and now I've changed my PT accordingly =P
serge could pyro circles around you
A challenge, eh? It'll be worth a game against him to see if he could, come to think of it.
Please.
Just under 150 kills, eh? I reckon it might be worth a shot.
And on a side note, I've just recognised who that is in your avatar- that's G1 Shockwave, isn't it?
Yes it is indeed. To be most precise, it came of this comic cover. Strange, the full count on my backpack lists my BB as having 1280 kills, rather than 150.

Sure, just charge it right.

So, a friend from school and I have been talking about antweights, so I'm going to try to finish this thing. He wants to make an AW as well.
So, all I need to know now is which battery pack to use and which charger to go with it. Should I use LiPo, or NiMh? If I use 7.4V, will the servos die? Etc.
I've settled on a Blue Bird BMS-380 MAX as a weapon servo. The cheapest I've found it for is £24.99 -shipping. Shipping outside the UK isn't really an option, long story.
IIRC, all I need are wheels, batteries and the other drive servo and the weapon servo, right?
Use a Lipo, think Hobby King servos, yes they can handle the volts, there you go.

I live in Canby.
But right now I'm in Greshem.
And some time today I was in Portland
What state do I live in?
Oregon.
There you go.

Online Metals is your friend, they have a huge selection of metal and plastic. You want to use 3/16 inch thick 4130 alloy steel, or Chrommoly as it's known more commonly as. That should get you something WAY better than that cheap ass aluminum flashing. PS: Hypnodisc started in the third wars, and ran a Lynch motor.

You would end up spending over 400 dollars what could be done better for 250.
Would it be worth it if I got the version without electronics?
Still no. Those motors are slow, and kinda cost a bit. Even the one with the lowest gearing only produces about 200 rpm, and cost 21.95 US dollars each. For the same price, four Harbor Freight 900 RPM drills will give you a tried and true drive motor, and a decent battery and charger. I'll leave other costs to other members because I went crabbing yesterday and my hands hurt.

First one I watched was Sewer Snake vs Raging Scotsman. It looks like people use flamethrowers to get around the active weapon requirement, if it's still enforced.
Or is that a sportsman class rule?
Sportsman class rule
The Mechanics
The robot chassis is made from heavy-duty anodized aluminum structural brackets and ultra-tough laser-cut Lexan panels. It includes four 12.0vdc 30:1 gear head motors and our 4.75" tires and wheels.
Speed's still a little slow (4 MPH), but I could upgrade that. I mainly want to know if it would be better to buy materials separately rather than using a Lynxmotion rover kit.
Where I read it was PVC. I still wouldn't buy it. It's mystery aluminumTM and lexan of unknown thickness and weighs "n". Most of the parts such as the motors, hubs, and esc would need to be replaced anyways.
I can attest to the killability of a Sabertooth. I've killed a 2x12 in a 3lb robot with serious shock mounting. Stuff just kinda pops off the board.
Probably a typo. The main product page is the best thing to look at, rather than the smaller ordering page.
Also, I've built Lynxmotion kits before (a BRAT 6DOF Biped, specifically) and at least for a biped the aluminum brackets hold up well. As for the Lexan, it's quarter-inch. The kit weighs 4.6 lbs altogether, so it would probably be a Hobbyweight.
I just want to know if it would cost me more to custom-build rather than just modify the chassis, and whether it would be worth the savings.
You would end up spending over 400 dollars what could be done better for 250.
